I have finally finished four more elements of mounted Early Imperial Romans. Three more elements of EIR Cv, and one element of Early Imperial Roman contariorum/catafractarii from post 100AD.
According to the DBM Army List Book 2, List 56...
A few alae of contarii/catafractarii were formed by Trajan and Hadrian. These did not have horse armour, but were armed with the long knotos, weilded in both hands unshielded.And so, all I did was select three Praetorian Cav figures, cut out, or off, their sword or spear, give them an identical horse pose, and add a kontos from 1/32" brass rod cut to 5cm length.
As far as DBx is concerned, I can use it in a DBA Middle Imperial Roman army (the figures for which I have put aside - whether or not I'll ever get round to using them is another matter!), or in a DBM Early Imperial Roman army (of which I am allowed a maximum of two - if I ever have another game of DBM) or, far more likely, in my HOTT EIR army.
Now to get back to painting the Praetorian legionaries.
